Application filed October 22, 1914.

11 York, borough of Manhattan, in the county and State of New York, haveinvented a new and Improved Sanitary Telephone Attachment, of which thefollowing is a full, clear, and exact description.

This invention relates to telephone appliances and deals moreparticularly with a sanitary attachment for transmitters.

The invention has for its general objects to improve and simplify theconstruction of transmitter attachments of the character referred to soas to be reliable and efficient in use, comparatively simple andinexpensive to manufacture, and so designed as to he easily and quicklyapplied to the mouthpiece of the transmitter and effectively retainedwhen once applied.

A further object of the invention is the provision of a telephonetransmitter having a novel arrangement of antiseptic holder which, inaddition to keeping the transmitter in a sanitary condition, conduces tothe clearness of the sounds directed into the transmitter.

With such objects in view, and others which will appear as thedescription proceeds, the invention comprises various novel features ofconstruction and arrangement of parts which will be set forth withparticularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of theinvention, and wherein similar characters of reference indicatecorresponding parts in all the views, Figure l is a central verticalsection of the attachment applied to the mouthpiece of a telephonetransmitter; Fig. 2 is a front view of the attachment; Fig. 3 is asectional view of the attaching ring removed; and Fig. 4 is a sectionalview of the antiseptic holder and sound clarifier.

Referring to the drawing, A designates an ordinary telephonetransmitter, to the mouthpiece l of which is applied the sanitaryattachment B, which is of such a nature that it can be easily andquickly applied Without the use of tools and without altering the formof the mouthpiece, so that the attachment is capable of universalapplication.

Specification of Letters Patent.

Serial no. 868,033.

The attachment comprises a metallic cup like body or shell 2, which, inits front surface, 15 provided with a central opening 3, and around theedge of the front plate is an annular rim 4 that is provided with aninternally-extending annular flange 5 at its rear. Within the shell orbody 2 is a holder for the antiseptic material. This holder comprisestwo circular pieces of wire gauze 6 and 7 suitably bound together attheir periphery, as by a clamping ring 8 which is spun or otherwiseformed around the pieces 6 and 7, as a binding. The wire mesh piece 7 1sbowed away from the other piece 6, and between the two is a lump or cake9 of suitable antiseptic material which is of such size thatconsiderable space is provided around it for the passage of sounds intothe transmitter. A rubber or other elastic ring 10 is disposed behindthe antiseptic holder and presses the same firmly against the front ofthe shell so that there is no danger of rat tling. This ring issubjected to compression by the turning in of the flange 5 of the shell,and thereby the periphery of this ring 10 is. tightly held in place.This ring in crosssection tapers inwardly to form a thin annular lip 11,and the internal diameter of the ring is considerably smaller than thediameter of the fiared end of the mouthpiece 1 of the telephonetransmitter, so that the said mouthpiece can be tightly engaged by theannular lip 11 when the mouthpiece is inserted in the opening of thering 10. Since the ring is made of rubber the lip 11 will readily yieldto permit the mouthpiece to be inserted, and when inserted theattachment is tightly held in place without being liable to rattle andcause a confusion of sounds in the transmitter. It will thus be seenthat the ring 10 performs two functions, namely, that of tightlyclamping in theshell the holder of the antiseptic material, and offirmly holding the attachment on the transmitter.

From the foregoing description taken in connection with the accompanyingdrawings, the advantages of the construction and method of operationwill be readily understood by those skilled in the art to which theinvention appertains, and while I have described the principle ofoperation, together with the device which I now consider to be the bestembodiment thereof, I desire to have it understood that the device shownopening, a holder for sanitary material dis posed in the shell, and aresilient ring clamped at its outer edge in the, shell and firmlysecuring the said holder in place, said ring being formed with aninternal yielding annular lip for engagement around the mouthpiece ofthe transmitter and forming the sole means for retaining the attachmenton the said mouthpiece. A

2. A sanitary attachment for telephone transmitters comprising a shellhaving an openjing, a holder for sanitary material disose lamped in theshell and firmly securing the said holder in place, said ring beingformed with an internal yielding annular lip for engagement around themouthpiece of the transmitter, said holder comprising two 1n the shell,and a resilient ringv wire gauze pieces bound together at their holderdisposed within the shell, and a ring arranged within the shell andengaging the periphery of the holder, said ring being of resilientmaterial and tapering inwardly .to form a yielding internal annular lipfor externally engaging the mouthpiece of a transmitter, said rim of theshell being provided with an internal annular flange at its rear,whereby the periphery of the ring is held under compression to clamp theantiseptic holiler tightly against the front plate of the she l.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
